HINGE CONSTRUCTION.

lpecioation of Letters Patent.

Patented Dec. 5, 1916.

Application led October 12, 1915. Serial No. 55,403.

To all whom. z't may concern:

Be it known that I, JOHN CUTHBan'r, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hinge Construction, of which the following is a specification.

My invention relates to hinges.

The general object of my invention is to provide an improved hinge.

A more specific object is to rovide a hinge for a fiushdoor or closure w ich is not visible from the flush or outside of the receptacle.

Other and further objects of my invention will become readily apparent, to persons skilled in the art, from a consideration of the followingl description when taken inv conjunction wit the drawin wherein:-

Figure 1 is a section ta en on line 1-1 of Fig. 2 showing a part of the receptacle structure and a flush door hinged thereto, the dotted lines showing the open position of the door or closure. Fig. 2 is a rear elevation. Fig. 3 is a section ta en on line3-3 of Fig. 2. Fig. 4 is a fra ent of an interior part of the structure s owing one of the hinge members. Fig. 5 is a complementary hinge member to be attached to t e door.

In all the views the same reference characters are employed to indicate similar parts.

I have shown my hinge construction in connection with a metal cabinet for containing panel board iittin and the like, for electric circuits. It is obvious, however, that it may be used for many other similar structures; in fact with any sort of a container or receptacle where it is desired that the door or closure should be even or flush with the outside surface thereof, and without showing the hinges on the outside of such structure.

6 is the outside wall of a cabinet or other structure to which the ush door 7 is hingpd. 8 is a jamb plate that is inse arably attac ed to the wall 6 as by spot wel ing or by rivets and bridges the margin of the opening or the joint where the door is hinged, thus providing a rabbet between saidplate and e of the doorwayv and'serving portion of the plate is .downturned, or inturned, as at 9 to orm members of the hinge. vEach inturned portion is provided with a segmental opening 10'which ex- 5 tends circumferentially or with substanthe inner ed tially uniform radius from the center of a groove 11.

The late 8 is provided with an integral mwar deflecting portion 8 which forms a partitlon dividing the receptacle into. two compartments, the inner one having as a base a panel board and the other, outer, annular compartment inclosing the hinges and w1r1ng connections and concealing them from view when the door is open. A hinge member 12 projects beyond the edge of the door and is downturned at its edge, as at 13, to provide flanges to give it strength and is provided on the edges at one of its ends with lateral projections 14-14 to enter the slots 10 of the confronting plates. The main body part of the member 12 is sufficiently wide to move freely between the downturned hin members 9-9 ofthe plate 8. The projectlng hinge member 12 is to be attached to the door 7, by spotv welding, rivets or the like, and in suchY relation that the projections 14 will sweep through the segmental slots 10 in the plates 8 when the edge 7 of the door 7 enters the groove 11.

A spring 15 is attached to the door 7 to yieldingly hold the door in closed position, as shown in Fig. 1. In the illustrated form it is secured at one end to the outer end of plate 12 and is bent in a U to lie with its other end bearing against the inner face of wall 8.

When the door 7 is open, as shown in dotted lines in Fig. 1, the edge 7 will enter the parallel groove or depression 11 in the jamb plate 8 while the projections 14 from the door-will sweep through the slots lO and be ided therein and serve to hold the door in its position when open. The spring 15 will close the door, when it is released, to be returned into the position shown in Fi 1.

Without the groove 11, in the jamb plate 8, the edge 7 of the door would ride over the adjacent edge of the wall 6 when the door is being opened. The groove 11 serves as a turning oint for the door and being the radial point for the slots 10, the projections 14 of the hinge member 12 move freely in the segmental slots without interposing any material resistance to the movement of the door.

It is, of course, manifest that my hinge mechanism may be applied to other structures or receptacles than cabinets and their closures.

groove parallel with and bridging the joint between said wall and receptacle closure at the hinged side; a closure, usli with the wall when closed, with its hinged edge overlying' said groove; a hinge member extending rom the closure beyond adjoining edges and a stationary hin e member secured to the inside ofthe wa l, serving as a guide when the edge of the closure is within said groove.

2. A closure hinge for a receptacle coinprising a jamb plate secured to the inner side of the receptacle wall and having a groove bridging the joint between said wall and receptacle closure at the hinge side, and parallel with said joint; a closure, Hush with the wall when closed, with its hinged edge overlying said groove; a hinged member exten ing from the closure be *ond adjoining edges and a hinge mem er comprising two confronting stationary plates secured to the inside of the wall serving as guides for the coperating closure member when the edge of the closure is within said groove.

3. A closure hinge for a receptacle, coinprising a jamb plate secured to the inner side' of the receptacle wall and having a groove bridging the joint between said wall and rece tacle closure at the hinged side and para lelwith said joint; a 'closure Hush with the wall when closed, with the hinged edge partially overlying said groove; a hinge plate member having lateral projections secured to the closure and extending beyond adjoining edges and a fixed hinge member comprising two confrontin parallel plates secured to the inside of ie wall and having segment shaped perforations into which the projections of the coperatinT hinge member extend, serving as guides therefor when the edge of the closure is within said glroove.

4. A closure inge for a receptacle opening comprising a wall, to an edge of which a closure is to be hinged; a jamb plate secured to the inner side yof the wall and extendin into the closure opening beyond the meetin edge of said closure and wall to bridge t e joint by thereby roviding a rabbet; a closure, Hush witliftfe wall, on the outside, when closed; apart projectin into' the receptacle from the inner edge' o said plate; and hinge members secured respectively to said closure and wall' on the inside of said receptacle and lying at all times inside of the rabbet.

5. A closure hinge for a receptacle opening comprising a Wall, to an edge of which a closure is to be hinged; a jamb plate secured to the inner side of the wall and extending into the opening beyond the meeting edge of the closure and wall; a closure flush with the wall on the outside when closed and adapted to swing about its edge bearing on the jamb plate as an axis; a projecting hinge member carried on the inner side of the closure adjacent said edge; and an arcuate guide carried on the inner face of the wall and engaged by said projectinor hinge member.

6. closure hinge for a receptacle o ening comprising a wall, to an edge of w ich a closure is to be hinged; a jamb plate secured to the inner edge of the wall and extending into the opening beyond the meeting edge of the closure and wall; a closure flush with the wall on the outside when closed and adapted to swing about its edge as an axis; a projecting hinge member carried on the inner side of the closure adjacent said edge; an arcuate guide carried on the inner face of the wall and engaged by said projecting hinge member; and means for resiliently holding said closure edge in contact with the adjacent wall edge.

7.
